Abstract: A novel waterborne epoxy ester emulsion was prepared. The synthesized emulsion and polyacrylate emulsion were used as film-forming substance, mixed further with pigments and coating additives to prepare waterborne industrial coatings. The structure of the resin was confirmed by Fourier transfer infrared (FT-IR), dynamic light scattering (DLS) and gel permeation chromatography (GPC) .The mechanism of the crosslinking process of the resin was discussed. Moreover, two different preparation processes for waterborne industrial coatings based on waterborne epoxy ester emulsion were investigated and compared. The waterborne industrial coatings with good compre hensive properties are obtained via optimization of preparation process thereof.
